Correlation between serum neurofilament light chain (sNfL) concentrations upon admission. a The number of days hospitalised. Each dot in the scatter plot represents a sample, Spearman’s correlation coefficient rs is 0.69 (p < 0.0001). b sNfL levels on admission in patients who did or did not require ICU (intensive care unit) transfer throughout their hospital stay. Box plots indicate median and IQR with whiskers extending 1.5 times the IQR. c Receiver operating characteristic (ROC) curve analysis for the probability of ICU transfer depending on sNfL levels on admission
